This report examines how State Energy Offices and state-level partners are supporting growth and uptake of Commercial Property Assessed Clean Energy (C-PACE) financing around the country. The report offers examples, insights, and strategies for State Energy Offices, green banks, state financing agencies, and other public and private entities to catalyze, accelerate, organize, and expand C-PACE markets.

This report explores how governments and energy efficiency implementers could help stakeholders better analyze and act upon building performance data to unlock savings.

This report is a guide to all customer-facing financing products—products offered by a lender directly to a borrower—used to pay for energy efficiency. Intended for state and local governments that are deciding whether to start a new program, tune up and existing program, or create a Green Bank, it provides information on the full range of financing product options for target participants, the tradeoffs of various products, and potential advantages and disadvantages for different types of customers.

This paper investigates the credit enhancement value of NYSERDA's on-bill energy efficiency financing program relative to its similar conventional unsecured loan program. In the raw data, while both loan pools perform well relative to credit card lending, the on-bill loans default more often than the unsecured loans. This paper shows that this result persists: on-bill loans default more often, and this finding is not sensitive to model specification. This paper also shows that NYSERDA's alternate underwriting mechanism based on mortgage and utility bill repayment history performs well, and that projected dollar savings from the installed projects do not significantly influence loan performance.

The report makes the case for establishment of common data collection practices for energy efficiency lending. The report reviews existing practices for the collection of four categories of data from energy efficiency financing programs: (1) customer data; (2) financial product and performance data; (3) facility-level data; and (4) energy efficiency project data. The report then identifies high-priority needs, characterizes potential uses for finance program data, and identifies use cases that describe how stakeholders use data for key objectives and actions.

This report provides an overview of considerations for designing and implementing successful energy efficiency financing programs for existing buildings in the residential and commercial sectors. Information on key issues related to energy efficiency financing programs, guidance to existing resources that provide more in-depth financing program design and implementation information, and strategies for delivering broad customer access to attractive financing products that enhance customer capacity and willingness to invest in energy efficiency to address "first cost" barriers are included.

There are more than 17 million multifamily households nationwide, yet they remain a significant and mostly untapped opportunity for energy efficiency gains. Many cities and states that have embraced energy retrofitting as a job creator and boon to both the environment and economy have yet to address potential savings in multifamily properties, primarily because of obstacles not faced by single family and commercial properties. This paper discusses two barriers -- a lack of information and financing -- that stand in the way of multifamily energy retrofits.

The objective of this document is to help state and local governments understand the role of program administrators (PAs) and assist them in developing successful partnerships with utility and other energy efficiency PAs. The majority of this paper presents information on partnering and leveraging current energy efficiency activities. However, it also includes information for governments in areas without active PAs, as well as an appendix with a case study describing how state and local governments can fill gaps and administer programs in the absence of a PA.

This report addresses a key bottleneck for private capital: lenders declining to underwrite energy efficiency loans for multifamily housing because they lack confidence in energy savings. It presents findings from an analysis of 230+ buildings, assesses total savings achieved and savings as a percentage of projections, and provides a starting point for an underwriting methodology.

This policy brief describes the energy efficiency financing options programs can use to help financial institutions make energy upgrades affordable and accessible to homeowners.

This U.S. Environmental Protection Agency resource is intended to help state and local governments design finance programs for their jurisdiction. It describes financing program options, key components of these programs, and factors to consider as they make decisions about getting started or updating their programs.

This publication outlines capital leveraging models and examples from across the country in which public funds were used to influence energy loan program capital.

This paper, which is based on detailed case studies of nine existing state and local programs, presents recommendations for energy upgrade programs to facilitate industry growth and support contractor business models.

This guide provides background on the home improvement market in the U.S. and Canada and end users and systems in existing homes, as well as a description of energy efficiency program approaches and strategies.

This guide helps states and localities develop voluntary or mandatory programs that go well beyond minimum code requirements for new buildings. It addresses energy efficiency materials and resource conservation, water efficiency, indoor environmental quality, and site development and land use.

This report provides comprehensive information on state, federal, local, and utility incentives and policies that are in place to support renewable energy and energy efficiency.
